William Henry Giles Kingston,
On the Banks of the Amazon
“ Still I could hear that ominous rattle as it shook its tail while moving along. Though its bite is generally fatal, it is easily avoided on shore, and seldom or never, I have heard, springs on a human being, or bites unless trodden on, or suddenly met with and attacked. In vain I looked for it. It kept moving about under the boughs, as I could tell by the sound of its rattle. Now it stopped, then went on again, now stopped again, and I dreaded every instant to see it spring out from its leafy covert toward us. I kept my gun ready to fire on it should I see it coming. ”
